Cars need safe and legal design more than ethics (4)

Driverless cars don't need ethics. What they do need is to be capable of following the rules of the road. The bits about not running into people are common sense. Leave the ethics to philosophers.

The wider point in this debate is that driverless cars wouldn't be distracted by mobile phones, drunk, drugged or irrationally aggressive. They would obey speed limits and not overtake dangerously. This would instantly save hundreds of lives.
